The arctic cooling fans are amazing. Right now they run at 700 rpm when the machine is at idle or light load and throttle up only as needed. I put them through a stress test and in the end I have less noise and a 4C drop in my peak core temps. Just amazing to me. So much better then the 800RPM Slipstreams and a Nexus PWM fan that would get very loud and still ended up with hotter temps the then lower rpm Arctic cooling fan I have now. I couldn't be happier. I have 5 120mm fans daisy chained. I am really really loving this setup.

Hi all,
I have a Scythe PWM 120mm fan, mounted in a PSU horizontally, and for the past couple of days, it's been making a lot of noise !! It sounds like a dying fan to me, like dust is in the motor... I guess I'm changing that fan soon....

Obviously a Gentle Typhoon. Preferably an AP-15. And then a few different models of Sanyo Denki fans. It doesn't really matter that much which ones. (Which model is used in the Seagate PSUs?) As long as they are Sanyo Denki San Ace fans. Also some Japan Servo fans, and Enermax Magma, and a Coolermaster R4. Clearly the Zalman ZM-F3 and S-Flex fans should have a good going over as well with your new test equipment. Choosing some fans from the top 10 list of Ehume's fan comparison would also be nice.

I've voted for other. I'd like a review of the brand new CoolerMaster Turbine Master, as I've read a couple of general reviews of this fan and it is seemignly an excellent performer but I'd like to see a review from a silence enthusiast perspective #

Xbits fan review are so non-helpful compared to SPCR. I'm not certain why that is. They seem to be done professionally. They are an interesting read. They just don't provide the insight and actionable information that the SPCR reviews do.

I'd love to see a review of quality quiet 180mm fans! Does Nexus, Scythe or Noctua have a 180mm fan in the future? Surely Silverstone aren't the only source of 180mm fans are they? I'd like to see fans that can fit in the raven / fortress ft-02 cases.

I think silvertstone is the only one with a 180mm fan... at least suitable for cooling a PC.

Scythe GT AP-15 (1850rpm), S-FLEX F (1600rpm), Kama Flow 2 H (1900rpm) and Zalman F3 (both Sleeve and FDB). It will be interesting to see how they compare at full speed and undervolted, especially the Scythes (which according to their site have roughly the same CFM, but different noise levels).

My preferences would be:

1) Arctic Cooling 32mm thick fans. I got a 92mm PWM model and must say that the quality is amazing. The mounting system is very good with no or little vibration at high RPM and the airflow is good. Maybe, even better than Slipstream at the comparable low noise level despite smaller diameter. And the price is totally kick-ass, it is probably one of the cheapest fans I have ever seen. I really consider switching all my exhaust fans to this model. But some deeper review on airflow would be really great.

2) Silverstone AP121/141. The AP181 is great at delivering airflow on long log distances, so these babies must be good as intakes as well. Considering a high price, I would like to know precisely how good they are though.

3) Various 140mm fans. I have not seen any good SPCR-level review of 140mm fans. So...

What I'm reading here.....The SS turns your sensor 856rpms @1262rpms. The Magma needs to turn 1565rpms to produce the same airflow? ......And at that rpm is 4.5dBA louder?

If that's the case, I cannot see any advantage to the Magma at all.

The Magma needs more RPM because it's a lower pitch fan. Lower pitch fans generally do well in higher backpressure situations. A low-pressure fan like the Slipstream can get noisier as the backpressure goes up, as I assume you've noticed when partially blocking a fan with your hand.

If there were no disadvantages to low-pressure fans, then every fan would be even higher-pitched than the Slipstream. I'm suggesting there are tradeoffs in different situations - the filters you need, but most folk don't use, are one special situation.

The Nexus Silent 120mm fan, very popular here at SPCR over the years, is the lowest-pitch 120mm fan I've encountered (in its YL guise). Takes a lot of RPM to push air. But very popular.

Felger Carbon above mentioned a version of the Yate Loon "the lowest-pitch 120mm fan I've encountered (in its YL guise)" with fan blades that he thought would generate more static pressure than its Nexus sibling at the cost of fewer CFM.

Given how important the Nexus reference fan is, I would like to see a review comparing it with its Petra and non-Petra cousin Yate Loons. (Petra Yate Loons appear to have their own unique type of fan blades).
